Space transportation is one of the most essential elements for enabling activities in space. For current rockets, reliability is too low and launch cost is too high when compared to aircraft operations. Reusable Launch Vehicles could solve these deficiencies and are being investigated by many companies. This book contains a databank of 300 worldwide suborbital and orbital Reusable Launch Vehicle concepts. It covers ideas from the first concepts, such as Silver Bird, proposed by Eugen Saenger in 1944, to present ones such as SpaceShipOne, proposed by Burt Rutan in 2003, as well as all X Prize candidates. For reader friendly use, all information is prepared in the same data style, which makes this book a unique reference for rocket scientists as well as everybody interested in and fascinated by rockets. An introduction to space transportation systems, a study on the motivation for developing Reusable Launch Vehicles and a discussion about the benefit of an international Reusable Launch Vehicle program complete this book.
